Absolutely and DANGEROUS. What you need to do is isolate the problem before fixing or replacing parts.
Disconnect the throttle cable. Push on the disconnected cable from the inside of your vehicle. Find out if cable is sticking.
If not, go to the disconnected throttle lever. Try to position it to stick. If it does stick there are several reasons. The TPS switch is binding and needs to be replaced, or the throttle plate may have a missing or loose screw. The screws are usually flared once they are installed and are not meant to be removed. Bad things if engine ate one.
The throttle housing may show signs of binding from the butterfly flap. If the housing was in an accident, the housing may be warped. Carbon buildup can jam action too.
Bad return spring on throttle housing. You need to replace spring or get different throttle body with a strong spring.
All of these parts should want to close more than to open.
Hello.....Try this.....follow the throttle cable down to the carburetor..Check the spring return for the throttle...Try to close the throttle by hand...If there is no spring..the throttle won't close by itself....If the spring is in place...Your cable may need adjusting or replacing...anyway....to me...it sounds like the spring....check it out and let me know....I hope this was helpful....PEACE....

Remove the carburetor cover and observe the action of the carburetor throttle arm as you actuate the throttle. If the arm doesn't move, disassemble the throttle trigger assembly (making part placement notes as you do so) and clean out any accumulation of sawdust/dirt. Make sure the cable or rod which connects it to the throttle arm will move--there should be spring return of the throttle arm to idle position. If this fixes the throttle problem, but the kill switch still doesn't work, you may have to remove the left side case to access the ignition module and the kill switch wire which plugs into the end of the module. The switch itself may be full of sawdust as well preventing contact to engine ground. Hope this helps!
Remove the air cleaner assembly so that you can see the action of the throttle mechanism. If nothing around the carburetor throttle arm is broken or out of place (the return spring), then remove the screws in the throttle trigger part of the handle and look for sawdust blocking throttle trigger action. Hope this helps!
Its a missing or broken spring in the handle(trigger). If you look inside the handle you should see a circular spring around the post of the trigger. This spring returns trigger to idle position. If its missing or broken the trigger won't spring back.
